VIII. An Account of a small Lobe of the human prostate Gland , 
which has not before been taken Notice of by Anatomists. By

Read February 20, 1806. 
Discoveries in the anatomy of the human body have been 
ever considered by this learned Society as deserving a place 
in the Philosophical Transactions : in the present improved 
state of our knowledge of this subject, a small addition to it 
cannot fail of being acceptable, since after the long continued 
labours of so many acute observers, such only can be ex- 
pected, and even those are rarely to be acquired. 
The subject of the present Paper is a portion of a gland, 
which from the obscurity of its situation has hitherto escaped 
observation : and were it not for the change produced in it 
by disease, which enlarges it so much that it sometimes com- 
pletely shuts up the canal, by which the urine ought to pass, 
it would be little deserving of attention : but when this im- 
portant effect is considered, the part itself becomes an object 
of very serious interest. 
In stating the circumstances, which led to the present inves- 
tigation, it may be necessary to mention that the prostate 
gland is liable in the latter period of life to enlarge : and 
when it does so there is frequently a nipple-like projection, 
which rises up and forms tumours of very different sizes in
